Leica 1.4x Extender that turns 400mm into 560mm.
The Leica Extender L 1.4x is purpose-built for the Vario-Elmar-SL 100-400mm f/5-6.3, extending its focal range to 140-560mm on the L mount. That extra reach matters in disciplines where closing the distance is not an option. The 1.4x magnification factor costs one stop of light, shifting the aperture range to approximately f/7 at the wide end. For photographers already working at the limits of the 400mm range, the jump to 560mm can mean the difference between a frame that works and one that doesn't.
This extender is a native L-mount accessory, designed to integrate with the Vario-Elmar-SL than adapt around it. The result is a dedicated pairing that preserves the lens's character across the extended focal range. For SL-system shooters who have already committed to the 100-400mm as their long telephoto, this extender is the logical way to extract more reach from glass they already own.
Who It's For
Wildlife photographers working from fixed positions, a hide, a boat, or a blind, gain practical distance from 560mm when subjects won't cooperate at 400mm. Sports shooters covering field events benefit from the tighter framing the 140-560mm range delivers at the long end. Travel and safari photographers carrying a single telephoto can extend their reach without adding a second lens body. Birders shooting in open landscapes where subjects are consistently far off will find the 1.4x factor pulls distant subjects into usable frame sizes.

FAQ
- What focal range does the 1.4x extender give me with the Vario-Elmar-SL 100-400mm?
- It extends the lens to 140-560mm. The 100mm wide end becomes 140mm, and the 400mm telephoto becomes 560mm.
- How much light do I lose when using this extender?
- A 1.4x extender costs one stop of light. The f/5-6.3 aperture becomes approximately f/7 at the wide end and f/9 at the telephoto end.
- Is this extender compatible with other L-mount lenses?
- The Extender L 1.4x is purpose-built for the Vario-Elmar-SL 100-400mm f/5-6.3. It integrates directly with that lens as a native L-mount pairing.
- Does the extender affect autofocus or image quality?
- The dedicated L-mount design preserves the lens's character across the extended focal range. AF performance depends on your camera body's capabilities at the reduced light levels.
- When would I use this extender instead of just cropping in post?
- The extender provides true optical magnification and maintains resolution at 560mm. Cropping loses pixels; this gives you more subject size in the frame before any digital intervention.
- How does a 1.4x extender compare to a 2x?
- A 1.4x adds one stop of light loss; a 2x costs two stops. For situations where you need reach but can't afford the aggressive light penalty of a 2x, the 1.4x strikes that balance.
